LB1638

Ordering number : EN3515C Monolithic Digital IC LB1638 LB1638M Overview Low-Voltage, Low-Saturation Bidirectional Motor Driver The LB1638, LB1638M are low-saturation bidirectional motor driver ICs for use in low-voltage applications. At an IO of 500mA, they have a low saturation output of VO(sat) = 0.75V. They are especially suited for use in compact motor of portable equipment. Features • Low voltage operation (2.5V min.) • Low saturation voltage (upper transistor + lower transistor residual voltage; at IO = 500mA, VO(sat) = 0.75V typ.) • Low current drain at standby mode (ICCO = 0.1µA typ. or less) • Separate logic power supply and motor power supply • Brake function • Built-in spark killer diodes Specifications Parameter Absolute Maximum Ratings at Ta = 25°C Symbol VCC max VS max Output applied voltage Input applied voltage Ground pin flow-out current Allowable power dissipation VOUT VIN IGND Pd max LB1638 LB1638M: Independent IC LB1638M: Mounted on a specified board Operating temperature Storage temperature Topr Tstg Conditions Ratings -0.3 to +10.5 -0.3 to +10.5 -0.3 to VS+VF -0.3 to +10.0 1.0 1.0 440 550 -20 to +75 -40 to +125 Unit V V V V A W mW mW °C °C Maximum supply voltage * Specified board: 30mm × 30mm × 1.5mm, glass epoxy board.
